ENAMELED spool. R BBB'IN.

SPECIFICATION forming part of Letters Patent No. 359,447. dated March 1,5, 1887.

Application filed August 27, 1886. Serial No. 2l1,969. (Model.)

To all whom it may concern.:

Be it known that I, SAMUEL D. KEENE, a citizen of the United States, residing at Providence, in the county of Providence and State of 5 Rhode Isl/and, have invented certain new and useful Improvements in Enameled Spools or Bobbins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled Io in the art to Whichrit'appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

I5 My'invention relates to certain improve-` ments in enameled spools or bobbins employed in the manufacture kof yarn and textile fabrics, the present invention consisting in the novel finish of the exterior enameled surface of the 2o spool or bobbin, as will be more fullyhereinafter set forth and claimed.

My invention is more particularly applicable to the surface ofwcoden spools or bobbins on which is wound the yarn used in the manu- 2 5 facture of textile goods, although it may be advantageously applied to roving-bobbins, &c.

Usually hereto fore the yarn-holding surfaces of spools and bobbins have been uniformly iinished-that is to say, in ametal bobbin or quill the surface is uniformly polished, in a wooden bobbin the surface is, if oiled or shellaced, uniformly treated, and if covered with Japan enamel applied in aliquid state the same, when baked, becomes smooth and uniform in finish and appearance.

I am aware that bobbins have been provided with a series of grooves or scores extending along the barrel thereof, such grooves being concentric, spiral, zigzag, 85e. Sand-paper, flannel, and leather have also been employed to prevent yarn from slipping off the bobbin. It is found practically that bobbins and spools thus treated and finished are objectionable, owing to the fact that the yarn, especially cotton yarn, is very apt to slide off from the smooth surface in masses, thereby producing a greater proportion of waste yarn, and the consequent increase in the cost of the manufactured fabric.

The extra cost of bobbius provided with grooves, 8vo., as just described, precludes their general use, while bobbins covered with sandpaper, leather, or ii'annel are too readily affected by steam or moisture to be desirable, aside from the increased cost in prqducing them. p41/ The object of my improvement herewith is to overcome the before-mentioned disadvantages by producing an enameled spool or bobbin having the yarn-retaining portion thereof 6o slightly roughened or dull7 nished, -by means of which the yarn is prevented from slipping off faster than is required, the end portion or tip of said spool at the same time having a smooth-finished surface, so that the yarn will not catch thereon in unwinding from the spool.

In order to more clearly set forth the distinguishing features of my invention, I,have prepared the annexed sheet of drawings, in 7o which- Figure 1 represents a perspective view of a bobbin embodying my improvements. Fig. 2 is a vertical central sectional viewof the same. Fig. 3 is a reduced side view showing the im- 75 provement applied to another style'of bobbin. Fig. 4 is a similar view of an ordinary Speederbobbin having smooth-finished ends and the intermediate portion of the bobbin dultiinished or roughened; and Fig. 5 is a View of a spool 8o thus enameled and finished.

`rlhe following is a more extended description of the invention. f

A, referring to the drawings, designates my 'improved' enameled bobbin or spool. 8 5

B indicates a layer or layers of Japan enamel covering the entire outer surface thereof, as well as lining the surface of the central longitudinal hole, c, as shown clearly in Fig. 2, said enameledcovering being baked or hard- 9o cned by a high degree of heat, as usual.

a designates the slightly-roughened or dullfinished portion of the enameled' spool, the same presenting what may be termed a mat7 surface. 95

A means for producing the'slightly-roughened enameled surface a is as follows: A varnish composed of japan, coarse lamp-black, naphtha, and oil is applied to the surface of the bobbin and then baked. By the addition 10o of fine emery to said varnish a 'coarser or more roughenedsurfaceisproduced. Substantially the same eect may be obtained, however, by submitting an ordinary enameled bobbin to the action of a revolving roll covered with sandpaper or other analogous material.

The tip or upper end portion of myimproved bobbin is covered with theJapan enamel proper and baked, the result being the smooth and hard-finished surface a.

AS is well-known, ordinary Japan enamel applied in a liquid state to wooden or metal articles and then subjected to the action of artificial heat produces a coating that is smooth and hard, yet tough, and being of great durability,even under constant use, such enameled wooden articles being, moreover, impervious to water, oil, steam, &c.

It is obvious that mineral paints of the colors desired, or bronze-powders even, may be combined with the Japan varnish to produce body colors.

In concluding, I would state I am aware that a wooden spool or bobbin having a baked enameled surface has been patented prior to my presentinvention. Therefore I do not broadly claim such enameled articles.

Having thus described my invention,what I claim as new, and desire to secure by United States Letters Patent, is-

1. Asa new article of manufacture, a spool or bobbin having a baked enameled exterior presenting a slight-ly-roughened or dull-finish surface to the yarn-retaining portion and a smooth-finish surface to the unwinding yarn, substantially as hereinbefore set forth.

2. The bobbin hereinbefore described, havingaportion of its exterior covered with baked enamel producinga roughened or dull surface, as at a, and the other or tip portion of the bobbin, as at a', covered with a baked enamel, producing a smooth, hard, and bright surface, substantially as shown and set forth.

3. A spool or bobbin having its end portions covered with smooth baked enamel and the portion intermediate of said ends covered with baked enamel having a slightly-Toughened or dull-finish surface, substantially as shown and described.

4. The wooden bobbin A, hereinbefore described, having its exterior surface covered with one or more layers, B, of Japan enamel baked thereon, the lower or yarn'holding portion of the enamel, a, having material combined therewith to produce a roughened or dead77 finished surface, while the upper por tion or tip, a, is covered with Japan enamel, producing a smooth, hard, and brilliant surface.

In testimony whereof I have affixed my signature in presence of two witnesses.
